KEEP WORK AREA CLEAN. Cluttered areas and benches invite injuries.
CONSIDER WORK AREA ENVIRONMENT. Don't use power tools
in
damp
or wet locations. Keep work area well
lit.
Don't expose power tools to rain.
Don't use tool
in
presence of flammable liquids or gases.
KEEP CHILDREN AWAY.
All
visitors should be kept away from work area.
Don't let visitors contact tool or extension cord.
STORE IDLE TOOLS. When not
in
use, tools should be stored in dry, and high
or locked-up place
-
out of reach of children.
DON'T FORCE TOOL.
It
will do the job better and safer at the rate for which
it
was intended.
USE RIGHT TOOL. Don't force small tool or attachment to do the job of a
heavy-duty tool. Don't use tool for purpose not intended.
DRESS PROPERLY. Don't wear loose clothing or jewelry. They can be caught
in moving parts. Rubber gloves and non-skid footwear are recommended
when working outdoors. Wear protective hair covering to contain long hair.
USE SAFETY GLASSES. Also use face or dust mask
if
cutting operation is
dusty.
DON'T ABUSE CORD. Never carry tool by cord or yank
it
to disconnect from
receptacle. Keep cord from heat, oil, and sharp edges.
SECURE WORK. Use clamps or a vise to hold work. It's safer than using
your hand and
it
frees both hands to operate tool.
DON'T OVERREACH. Keep proper footing and balance at all times.
MAINTAIN TOOLS WITH CARE. Keep tools sharp and clean for better and
safer performance. Follow instructions for lubricating and changing acces-
sories. Inspect tool cords periodically and
if
damaged, have repaired by autho-
rized service facility. Inspect extension cords periodically and replace if
damaged. Keep handles dry, clean, and free from oil and grease.
DISCONNECT TOOLS. When not in use, before servicing, and when chang-
ing accessories, such as blades, bits, cutters.
14.
REMOVE ADJUSTING KEYS AND WRENCHES. Form habit of checking to
see that keys and adjusting wrenches are removed from
tool
before turning
it
on.
15.
AVOID UNINTENTIONAL STARTING. Don't carry plugged-in tool with finger
on switch. Be sure switch is OFF when plugging
in.
16.
OUTDOOR USE EXTENSION CORDS. When tool is used outdoors, use only
extension cords intended for use outdoors and
so
marked.
17.
STAY ALERT. Watch what you are doing, use common sense. Don't operate
tool when you are tired.
18.
CHECK DAMAGED PARTS. Before further use of the tool, a guard or other
part that
is
damaged should be carefully checked to determine that
it
will
operate properly and perform its intended function. Check for alignment of
moving parts, binding of moving parts, breakage of parts, mounting, and
any other conditions that may affect its operation. A guard or other part
that is damaged should be properly repaired or replaced by an authorized
service center unless otherwise indicated elsewhere in this instruction
manual. Have defective switches replaced by authorized service center. Don't
use tool if switch does not turn
it
on and off.
19.
GUARD AGAINST ELECTRIC SHOCK. Prevent body contact with grounded
surfaces. For example; pipes, radiators, ranges, refrigerator enclosures.
20.
REPLACEMENT PARTS. When servicing, use only identical replacement parts.
21.
POLARIZED PLUGS. To reduce the risk of electric shock, this equipment has
a polarized plug (one blade is wider than the other). This plug will fit
in
a
polarized outlet only one way. If the plug does not
fit
fully in the outlet,
reverse the plug. If
it
still does not
fit,
contact a qualified electrician to install
the proper outlet.
Do
not change the plug in any way.
VOLTAGE WARNING: Before connecting the tool to a power source (receptacle,
outlet, etc.) be sure the voltage supplied is the same as that specified on the
nameplate of the tool. A power source with voltage greater than that specified
for the tool can result in SERIOUS INJURY to the user
-
as well as damage to
the tool.
If
in doubt,
DO
NOT PLUG IN THE TOOL. Using a power source with
voltage less than the nameplate rating is harmful to the motor.

ADDITIONAL SAFETY RULES
1.
Wear a hard hat (safety helmet), safety glasses and/or face shield.
It
is also
highly recommended that you wear a dust mask, ear protectors and thickly
padded gloves.
2.
Be sure the bit is secured
in
place before operation.
3.
Under normal operation, the tool is designed to produce vibration. The screws
can come loose easily, causing a breakdown or accident. Check tightness
of screws carefully before operation.
4.
In
cold weather or when the tool has not been used for a long time, let the
tool warm up for a while by operating
it
under no load. This
will
loosen up
the lubrication. Without proper warm-up, hammering operation is difficult.
Be sure no one is below when using the tool in high locations.
5.
Always be sure you have a firm footing.
6.
Hold the tool firmly with both hands.
7.
Keep hands away from moving parts.
8.
Do
not leave the tool running. Operate the tool only when hand-held.
9.
Do
not point the tool at any one
in
the area when operating. The bit could
fly out and injure someone seriously.
IO.
When chipping into walls, floors or wherever "live" electrical wires may be
encountered,
DO
NOT TOUCH ANY METAL PARTS
OF
THE TOOL!
Hold the tool by the insulated grasping surfaces to prevent electric shock
if you chip into a "live" wire.
11.
Do
not touch the bit or parts close to the bit immediately after operation;
they may be extremely hot and could burn your skin.
SAVE THESE INSTRUCTIONS.

MAINTENANCE
CAUTION
:
Always be sure that the tool
is
switched off and unplugged before attempting to perform
inspection or maintenance.
Replacing carbon brushes
When the resin insulating tip inside the
carbon brush
is
exposed to contact the
commutator,
it
will automatically shut off
the motor. When this occurs, both carbon
brushes should be replaced
at
the same
time. Use only identical carbon brushes.
Insulating tip
Use
a
screwdriver to remove the holder cap
plates.

oz.)
CAUTION
:
Filling with more than the specified
amount of grease (approx.
30
g;
1
02.)
can cause faulty hammering action or
tool failure. Fill only with the specified
